PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 498,851, dated June 6,1893.

Application filed November '7, 1892. Serial No. 451.236- (No model.)

To all whom it may concern:

Be it known that I, JOHN M. JONES, a citizen of the United States,residing at Palmyra, in the county ofWayne and State of New York, haveinvented certain new and useful Improvements in Printing-Presses, ofwhich the following is a specification.

My invention relates to printing presses, and has reference moreparticularly to that class of presses known as the Gordon press,

in which the bed reciprocates toward and from an oscillating platen.

In the present invention, an inking cylinder orroller, in lieu of arotatable inking disk, is mounted in the reciprocating bed; and theroller-frame carrying the form-inking rollers, is so arranged andconnected that when thethrow-oif lever is moved backward to throw offthe impression, the said rollerframe will also be prevented fromtraversing the form and will remain in such position that its rollersmay have contact with the main inking cylinder for the distribution ofink..

In the drawings,-Figu rel isa perspective View of a Gordon press showingmyimprovements applied thereto, the inking rollers being shown as incontact with the inking cylinder; Fig. 2, a face view looking at theopposite side, the inking rollers being represented as having justdescended over the form; Fig. 3, a view illustrating certain detailshereinafter set forth.

A indicates the main frame, which may be of most any desiredconstruction. In the main frame is mounted the platen B, and the shaft0, which latter carries the crank wheels D and E. These wheels D and Eare connected by pitmen F with a shaft G mounted in the upper end of thebed H, which bed is hinged or pivoted at its lower end to the mainframe. Wheel F. gears into a small pinion e on the main shaft J, towhich motion is imparted from any suitable source of power.

Shaft G is provided at one end with an arm a which carries a rod 6; thelower end of the rod 1) being connected to a lever c pivoted to the mainframe. The throw-off lever I, pivoted in the main frame, is connected bya link or rod 01 with the short lever 0, so that when the lever I ismoved away from the operator, it will, acting through the connectionscl, 0, b, a, and the eccentrics on shaft G bring the parts into theadjustment required preparatory to making an impression. On the otherhand, when the lever I is thrown toward the operator, the parts will bebrought into such adjustment as to preclude the type from making animpression. This will. be better understood upon reference to my patentsnumbered 379,958 and 450,368, in one of which the mechanism herein shownis more fully described. Most any form of throw-off mechanism may besubstituted for that shown, and hence I have here given only a generaldescription of the mechanism which I will refer to as the throw-offmechanism.

Mounted upon thecrank shaft J isa sprocket wheelfabout which and adouble sprocket g at the base of the main frame, achain hpasses, asshown in Fig. 1. A second chain 2', passing at its lower end about wheelg, also passes over a wheel j secured upon the end of the shaft is ofthe inking cylinder K, the said cylinder being journaled in the upperend of the bed H. The double sprocket wheel g is mounted upon the pivotconnecting the bed and the main frame so that the reciprocation of thebed will not afiect the gearing. Belting or any other form of gearingmay be substituted for the sprocket wheels and chains. From theforegoing, it will be seen that the ink-cylinder will have a continuousrotary motion regardless of the adjustment of the impression throw-offmechanism.

L indicates the frame, carriage, or carrier in which the form-inkingrollers Z are mount: ed, and M, M, indicate two rods or links connectingthis frame with the arms N, N, of a shaft 0 hung in suitable bearings inthe main frame; the connection being such that when .the shaft isoscillated in one direction and the arms thrown upward, the roller-framewill be brought to the position shown in Fig. 1, but when the shaft isoscillated in the reverse direction, the arms will be thrown downward,andthe roller-frame brought to the position shown in Fig. 2, the rollersinking the form in both the up and down movements.

In order to actuate the shaft 0, I employ a connection between the bedand the shaft. This connection may be variously modified withoutdeparting from my invention, but a convenient construction isillustrated in Figs. 2 and 3, and will now be described. On one end ofshaft 0 is an arm mto which is pivotally at tached one end of a linkorbar P, the opposite end of which is shown in the present instance asbeing connected to the shaft G. Now, of course, when the bed movestoward the main frame, the shaft 0, through arm mand bar P, will berocked or oscillated in one direction, but when the bed moves away fromthe frame, these same connections will oscillate or rock the shaft inthe opposite direction, thus imparting to the roller-frame the desiredmovments. hen the impression is thrown off, it is desirable that theroller-frame shall remain in its elevated position with'the rollers incontact with the ink cylinder, and to secure this result, 1 make the baror connection P extensible lengthwise and provide it with means wherebywhen the impression is on the bar shall be rendered non-extensible, butwhen the impression is otf,'the bar shall be extensible and by itsextension prevent the rockingof shaft 0. This will best be understoodupon referenceto :Figs. 2 and 3, in-which it will'be seen'thatthe bar Pismade in two parts or sections it and 0, one of which, n, is secured toshaft G or to any other part of the :bed, while the other section, 0,has'a sliding connection with the section '11. Section oisprovided witha latch 13 designed to engage the section a and lock the two parts ofthe bar together so that theys'hall movetogether as connecting the armsN, N,'with the rollerone.

"In order to actuate the latch when the impression is .thrownoff,Iconnect with a-member of the throw-off mechanism, preferably theshort lever c,a rod (1 which is connected at itsupper end with the latch19. When the throw-off lever I is moved forward to throw on theimpression, the rod qwill draw the latchdownto engage the section 0, andthuslock the two parts of the bar P together; but. whenthe impression isthrown ed by a reverse movementof the lever -I,the rodiq will raise thelatch, and thereby disconnect the two parts-of thebar'P. 'When'thusreleased,; the section 0 of the bar P will, as the bed re-v ciprocatestoward and from the mainframe, slide upon-and relatively to the mainsection 'n-without rocking the shaft 0 and without causing any travel ofthe roller-frame.

position.

Having thus described my invention, what I c1aim-is 1. In combinationwith the main frame, platen, and pivotedbed, a rotating ink cylin-- dermounted in the bed, a roller-frame provided with'inking rollers, meansfor causing:

spring r secured at one end to an arm 8 on' shaft O, and at the oppositeend tothe frame. 5 tends to keep the roller-frame in its elevated latch.

a travel of the said frame, a throw-off mechanism and a connectionbetween the throwoff mechanism and the means for causing a travel of theroller frame, whereby when the impression is thrown off the said meansare also thrown out of action.

2. In combination with the main frame, platen, and pivoted bed, arotating ink cylinder, mounted in the bed, a roller frame, connectionssubstantially such as shown and described for actuating theroller-frame, an impression throw-off mechanism having connection withthe frame -actuating devices whereby the throwing off of the impressionshall automatically throw the frame-actuating devices out of action andaspring to cause the said frame to remain in itselevated position.

3. In combination with the-mainframe and platen; the xpivotedibed andits inking cylinder; the roller-frame :provided with rollers; anextensible device for actuating the rollerframe; a lock for the saiddevice, andan impression-throw-ofi mechanismand intermediate connectionsarranged :to actuate thelock or latch.
